Taking Chaobai River Bridge in Jingcheng Expressway as the engineering background, the article introduces the selection process of 3-phlon partial cable-stayed bridge structural system, and through the numerical analysis, compares the reactions of the different structural systems under the external action, and uses the measures using damper to reduce the earthquake effect of the structure.

In this paper, we describe precise mathematical structures intended to idealize the physical notion of continuous body and deal with what we call the external action and internal interaction.

The Confucians' value and their existence reasons neither depend on one economic formation nor on the effectiveness of their external action, but on their internal transcendence of significance provided by the life world.

The rule of the change of the viscosity of polyether polyols and glass fiber/polyether polyols with temperature fluctuation was studied, the effect of glass fiber content on the viscosity of the mixing system was discussed, and the dispersion of glass fiber/polyether polyols under external action was studied by means of planet stirrer.

The article states what I get from my thoughts and probes on external action and expression of inner feelings,grasp of rythem of action and problems of demonstration directors.

The first initial boundary value problem is considered for a hyperbolic equation with a small parameter for an external action described by some stochastic process satisfying some of the conditions of weak dependence.

The first initial-boundary problem for a parabolic equation with a small parameter under external action described by some random process satisfying an arbitrary condition of weak dependence is considered.

The first initial-boundary problem for a parabolic equation with a small parameter under external action described by some random process satisfying an arbitrary condition of weak dependence is considered.

The input image is transformed into a stationary structure dependent on the form of the coupling function and the type of the element's response to external action.

Chaotic self-oscillations in a generator with inertial nonlinearity under parametric external action

In this paper, we describe precise mathematical structures intended to idealize the physical notion of continuous body and deal with what we call the external action and internal interaction. The following result is obtained by applying the representation theorem: A rheological process can be characterized by a triple (χ, β, T), where χ:(?)×T→(?) is a kinematical process of body (?),β: (?)×T→ (?) a reference process of the external world (?). and T:(?)×T→Sym ((?))a symmetric stress tensor field....

And finally, we definite a thermodynamic process as a septuple (χ, β, f, E, H, S, O) and derive a result for this process analogous to the theological processes, i. e. every thermodynamical process could be characterized by a septuple (χ,β, T, ε, q.η, θ), where T,ε, q, η,θ, are functions on(?)×T representing the stress, energy density, heat flux, entropy density and temperature corresponding to the actual placements of the motion determined by χ and β.

Some aspects of the perceptual motor abilities of mentally retarded (MR) children were studied by comparing 17 normal children with 31 children of slight, medium, and severe retardation. Two hole I drilling tasks with different levels of difficulty were designed. In Task 1, subjects were asked to drill a hole through the utilization of bi manual coordination, while in Task 2 subjects were asked to drill a hole by using bi manual foot coordination. The results showed that there were significant differences...

Some aspects of the perceptual motor abilities of mentally retarded (MR) children were studied by comparing 17 normal children with 31 children of slight, medium, and severe retardation. Two hole I drilling tasks with different levels of difficulty were designed. In Task 1, subjects were asked to drill a hole through the utilization of bi manual coordination, while in Task 2 subjects were asked to drill a hole by using bi manual foot coordination. The results showed that there were significant differences in several kinds of performance between MR and normal children: 1) MR children, especially children of medium and severe retardation, were worse at comprehending the task and their imitation ability was poorer than that of normal children. As the task became more difficult, the differences between the two groups of children became larger. 2) The coordination ability of MR children stayed at a primary or moderate level while the normal children's motor coordination ability remained at a moderate or high level. This limitation of the mentally retarded children's coordination ability may have caused some of these children to have great difficulties in Task 2. 3) The speed of performance decreased with the level of mental impairment, especially in Task 2. Significant differences in performance speed were observed between the medium retardation level and the normal level, between slight and medium retardation, and between medium and severe retardation. 4) The performance accuracy for the right hand did not show significant differences between medium retardation children and normal children in Task 1, but did in Task 2. For the severely retarded children, the performance accuracy were very low in both tasks. Since the operation with the left hand was very easy, the differences in performance among the four groups were not significant. 5) Some characteristics of MR children in the perceptual-motor performance were as follows: (1) their external action was clumsy, slow, inflexible, and inaccurate; their level of coordination was poor, and the learned action was hard to transfer to a new situation, (2) their perceptual span was small, and both comprehension and long term memory were poor.

In this paper, an improvement on the existing quantitative hazard evaluation method (BZA-1 method) to evaluate the plants of explosive,propellant or ammunition was pro-posed according to the theory of explosion and the composition and speciality of explosive. The substantial risk index α was replaced by the sensitivity parametric value q/Ea-an explosion degree indication of explosion dangerous source under external action. The advancement extents the appli-cation range of BZA-1 method.[
